TECHNICAL FIELD
[0001] The present application relates to the technical field of wind power generators, in particular to a vertical axis stacked tower low-speed high-efficiency wind power generator. BACKGROUND
[0002] In recent years, with the rapid growth of renewable energy demand, wind power technology has been widely developed and applied. Most of the existing wind power generators adopt horizontal axis structure, which is characterized by high speed under high wind speed conditions, high energy conversion efficiency, but poor performance in low wind speed area, difficult to realize stable start and effective power generation. In addition, horizontal axis fan generally occupies large area, has high requirement for installation environment, equipment volume is large and maintenance cost is high, which is not conducive to popularization in small and medium-sized scenes or low wind speed area.
[0003] Compared with the horizontal axis wind power generator, the vertical axis wind power generator has the advantages of compact structure, small influence of wind direction, convenient maintenance and the like, and is suitable for areas with variable wind direction or low wind speed. However, the existing vertical axis wind power device still has problems: firstly, most of the vertical axis structures have low torque under low wind speed, are difficult to start, and have low wind energy utilization rate; secondly, the tower body is easy to produce vortex and lateral vibration in operation, so that the structural stability is affected; thirdly, in the multi-layer structure or large-scale application of the vertical axis fan, the airflow interference between the fan blades is obvious, which leads to the decrease of aerodynamic efficiency; in addition, the heat dissipation mode of the traditional generator is single, which cannot meet the heat dissipation demand under the continuous power generation condition, thereby limiting the reliability and service life of the system.
[0004] In the prior art, the multi-layer stacked tower structure, the composite fan blade array, the wind resistance reduction structure and the active heat dissipation structure have not been effectively combined. Especially under low speed working condition, how to realize high torque output, improve the wind resistance performance of the tower body, optimize the air guide mode and realize the efficient heat dissipation of the generator body is still a problem to be solved in the vertical axis wind power technology. Therefore, there is an urgent need for a new type of vertical axis wind power device with more reasonable structure, higher wind energy utilization rate, more stable operation and stronger heat dissipation capacity, so as to overcome the limitations of the prior art and improve the application value of wind power in low wind speed area.

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.
[0028] Please refer to Figures 1 to 4 The embodiment provides a technical solution: a vertical axis tower type low-rotating-speed high-efficiency wind driven generator, which comprises: a plurality of connecting strips 112 fixedly installed on the outer surface of a rotating rod 111, a low-speed high-torque energy absorption is realized through a planar fan blade array formed by fans 113, and a support-force transmission structure similar to an aeroengine steel wire series connection is formed by the connecting strips 112, the rotating rod 111, a convex rod 110 and a convex ring 109, so that the multiple layers of fan blades keep a stable posture in the rotating process, and the driving efficiency is ensured; the overall structure is installed on a base 101, a tower type stacked support frame is formed through a support frame 102, and a tower type elastic ball 103 is arranged on the outer side, so as to reduce the wind resistance of the tower body, decompose the lateral airflow impact and improve the overall steady-state operation capability.
[0029] As Figures 1 to 4 shown in the drawings, in one embodiment, a plurality of fans 113 are rotatably installed on the top of the plurality of connecting strips 112, the plurality of fans 113 are arranged side by side, a lightning rod 117 is installed on the top of the rotating rod 111, the fan blade array is guided and controlled by the rotating rod 111 and the connecting strip 112 guide structure, the fans 113 rotate with the rotation of the wind direction, so that the cold air with high density forms a directional vortex and directly sweeps the outer wall of the generator body 104, heat dissipation is realized, and the lightning rod 117 located at the top can effectively realize lightning protection.
[0030] As Figures 1 to 4As shown, in one embodiment, the bottom end of the rotating rod 111 is hollow, and a convex ring 109 for limiting the rotation rod 111 is fixedly installed on the outer surface of the convex rod 110. An insertion hole 106 is opened on the outer surface of the rotating shaft 105. The hollow bottom end of the rotating rod 111 facilitates insertion into the outer surface of the convex rod 110. The convex ring 109 limits the rotation rod 111 and prevents the rotation rod 111 from moving downward on the outer surface of the convex rod 110.
[0031] like Figures 1 to 4 As shown, in one embodiment, an L-shaped fixing plate 114 is fixedly installed at the bottom of the rotating rod 111. An insert rod 115 is movably embedded inside the L-shaped fixing plate 114. A limiting hole 116 is opened on the outer surface of the insert rod 115. The insert rod 115 is movably embedded inside the insertion hole 106. The rotating rod 111 is inserted into the outer surface of the protrusion 110, and then the insert rod 115 is inserted into the insertion hole 106 to limit and fix the rotating rod 111.
[0032] like Figures 1 to 4 As shown, in one embodiment, an L-shaped fixing plate 107 is fixedly installed on the outer surface of the rotating shaft 105. A threaded rod 108 is movably embedded inside the L-shaped fixing plate 107. The threaded rod 108 is movably embedded inside the limiting hole 116 to limit the insertion rod 115 and prevent the insertion rod 115 from sliding laterally inside the insertion hole 106. When the threaded rod 108 is rotated, it moves inside the L-shaped fixing plate 107. When moving, the threaded rod 108 is inserted into the limiting hole 116, thereby limiting the insertion rod 115. Through the above, the rotating rod 111 can be disassembled and installed. After the rotating rod 111 is separated from the rotating shaft 105, it is easy to transport.

A support-transmission structure, similar to the steel wire connection in an aircraft engine, is formed by connecting bars 112, rotating rods 111, convex rods 110, and convex rings 109. This ensures the multi-layered fan blades maintain a stable posture during rotation, guaranteeing drive efficiency. The entire structure is mounted on the base 101, forming a tower-like stacked support frame via support frame 102. Tower-like elastic balls 103 are arranged on the outer side to reduce tower drag, decompose lateral airflow impact, and improve overall steady-state operation. In terms of airflow management, the fan blade array regulates airflow direction through the rotating rods 111 and connecting bars 112. Fan 113 rotates with the wind direction, causing denser, cold air to form a directional vortex that directly blows onto the outer wall of the generator body 104, achieving heat dissipation. A socket 106 is provided at the top of the tower for connecting functional components, and a lightning rod 117 forms part of the protection and safety system, ensuring reliable operation of the entire unit in large-scale deployment scenarios.
[0034] The rotating rod 111 is inserted into the outer surface of the convex rod 110, and is limited by the convex ring 109 to prevent the rotating rod 111 from moving downward on the outer surface of the convex rod 110, then the inserting rod 115 is inserted into the inside of the insertion hole 106 to limit and fix the rotating rod 111, the rotating threaded rod 108 moves in the inside of the L-shaped fixed plate 107, and when moving, the threaded rod 108 is inserted into the limiting hole 116 to limit the inserting rod 115, and the rotating rod 111 can be disassembled and assembled through the above, which is convenient for transportation.
